| 摘 要： | 通过对流域河网二维水流模拟问题的分析,提出了一个通用化的河网二维模拟概化模式,该模式将河网二维概化为"树状"河道计算单元、"环状"河道计算单元、"十字型"河道计算单元等河网二维基本单元,对这些河道计算单元的求解,构建流域型河网一二维耦合模式的求解模型,并由此建立了通用化的河网二维水流数学模型软件系统。通过"树状"河道二维计算单元求解模型的推导与实现,验证了概化模式的可行性,表明该思路可以应用于大型流域河网一、二维水流模拟,具有很好的应用推广价值。

| Abstract: | By analyzing the 2-D river-network numerical model,a generic 2-D river-network numerical model is brought forward.In this mode,the 2-D river-network is combined with the several cells which include "tree like" river cell,"ring-like" river cell,and "cross-like" river cell.By disposing these cells,1-D river-network coupling with 2-D can be easily simulated,and a soft system about generic 2-D river network's numerical model is built.Derivation and realization of the "tree-like" cell calculation model shows that the method is very valuable and can be applied to the large-scale simulat ion of 1-D and 2-D river network. |
